What Is a Hub Flange?

The wheel hub is a barrel-shaped metal part that supports the tire inside the tire and is centrally mounted on the shaft. Also called rim, steel rim, cymbal, tire bell. There are many different types of wheels according to diameter, width, molding method and materials.

The wheel hub is also called rim. According to the characteristics and requirements of different models, the wheel surface treatment process will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The wheels of ordinary models have less consideration in appearance, and good heat dissipation is a basic requirement. The process is basically treated with baking paint, that is, spraying and then baking. The color of the wheel remains unchanged. The surface treatment of many Volkswagen models is painted. Some stylish avant-garde and dynamic colored wheels also use baking paint technology. These wheels are affordable and complete in specifications. Plating wheels are divided into silver plating, water plating and pure plating.

There are three methods of manufacturing aluminum alloy wheels: gravity casting, forging, and low-pressure precision casting. 1. Gravity casting method uses gravity to cast the aluminum alloy solution into the mold, and after processing, it is processed and polished by a lathe to complete the production. The manufacturing process is relatively simple, no precise casting process is required, the cost is low and the production efficiency is high, but it is easy to generate bubbles (trachoma), the density is uneven, and the surface smoothness is insufficient. A lot of Geely models are equipped with wheels produced by this method, which are mainly early models. Most new models have been replaced with new wheels. 2. Forging method The entire aluminum ingot is directly extruded on the mold by a 1,000-ton press. The advantages are uniform density, smooth and meticulous surface, thin and light-weight hub wall, and the highest material strength. Due to the need for more sophisticated production equipment, and the yield is only 50% to 60%, the manufacturing cost is higher. 3. Low-pressure precision casting method Precision casting at a low pressure of 0.1Mpa. This casting method has good formability, clear contours, uniform density, and smooth surface. It can achieve high strength, light weight, control costs, and yield. Above 90%, it is the mainstream manufacturing method of high-quality aluminum alloy wheels. ^[1]

1. Wheel rim: It cooperates with the tire assembly to support the wheel part of the tire. 2. Spokes: Installation and connection with the axle hub to support the wheel part of the rim. 3. Offset: The distance from the center surface of the rim to the mounting surface of the spokes. There are positive offset, zero offset, and negative offset. 4. Rim: The rim part that holds and supports the tire. 5. Bead seat: Also known as the mounting surface, it is in contact with the rim and supports the rim part that maintains the tire radial direction. 6. Bottom of the groove: In order to facilitate the assembling and disassembling of the tire, a pit with a certain depth and width is left on the rim. 7. Valve hole: Hole for installing the valve of the tire. ^[1]

A wheel includes many parameters, and each parameter will affect the use of the vehicle, so in

There are three factors to consider when choosing a wheel.

In the use and installation of hub bearings, please pay attention to the following: 1. In order to ensure maximum safety and reliability, it is recommended that you check the hub bearings frequently regardless of the age of the vehicle-pay attention to whether the bearings have

1, buy cheap fakes

The modification of the wheel hub is a relatively important step in the modification of the car. Whether it is the appearance modification or the improvement of the handling performance, the wheel hub plays an important role in it. Its personality parameters are qualified. Of course, a set of genuine wheels are expensive, and only a handful of domestic companies can produce and sell domestically (with export products), so the imported wheels are more expensive. Therefore, in order to save costs, many modified players choose so-called "domestic" and "Taiwan-made" fake wheels, which is completely undesirable. If it is a "small workshop" fake wheel, although the appearance is not much different from the genuine wheel , But the weight, strength and other aspects are far from reaching the safety index. There are often problems such as cracks and deformation when players use "imitation" wheels, and in the high-speed process, fakes are not enough. Supporting such a large-intensity load, if there is a phenomenon of high-speed burst, it will directly affect the life safety of the driver and passengers! Therefore, it is particularly reminded that if economic conditions temporarily do not allow it, please choose a modified wheel carefully. Although the original "steel rim" and "casting wheel" may not be beautiful and lightweight, at least the safety is guaranteed. . Wheel performance is generally forged wheels> cast wheels> steel wheels. ^[1]

In the first step, check the scar. If there is no damage to the inside of the hub, you can simply repair it. Use paint diluent to wipe around the scar to remove the dirt. In the second step, the deepest part of the scratch is difficult to remove the dirt. It can be thoroughly cleaned with a toothpick. Step 3: In order to prevent the irrelevant parts from being painted by mistake, it is best to stick the adhesive tape around the wound carefully. Step 4. Finish the tip of the brush and apply decorative paint. After drying, the paint shrinks a little, and it is better to apply a little convex. The fifth step, after coating, it takes about a week to completely dry. After drying, dipped in soapy water with a water-resistant paper to smooth the surface. In the sixth step, after rubbing with water-resistant paper, wipe off the light with the mixture, and then wax it. ^[1]
